Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof; the rear elevational view thereof, top plan view thereof, and bottom plan view thereof are identical to the front elevational view.

FIG. 3 is a left side view thereof; the right side view is identical to the left side perspective view.

FIG. 4 is an enlarged fragmentary view from upper 4-4 to lower 4-4 in FIG. 2; and,

FIG. 5 is an enlarged fragmentary view from upper 5-5 to lower 5-5 in FIG. 2.

The broken lines illustrate environmental subject matter only and form no part of the claimed design. The dash-dot-dash broken lines define the boundary of the tire tread and form no part of the claimed design. The surface shading lines and stippling in the drawings depict the character or contour of the surfaces represented and form no part of the claimed design. 

CLAIM The ornamental design for a tire tread, as shown and described.
